I have a new ZWO 36mm 7 position filter wheel. I've run some test sequences using 36mm unmounted chroma filters (3mm thick) and have noticed that the 2, 3, and 4 position filters are intermittently slewing to a not quite correct position - there is uneven flat correction in opposing corners that comes and goes. The sequence is set so that the wheel should slew in one direction going from 0 - 1 - 2 - 3 - 4.
I plan on checking to make sure that the filter masks are well seated tonight and not potentially obstructing the wheel housing and recalibrate the filter wheel per another thread on this forum. Are there any other mechanical issues I should be looking for to address this?
